GASOLINE THIE F PROOF AEPLIANCE Filed May 9, 1932 INVENTOR ATTORN EYPatented Oct. 17, 1933 UNITED STATES PATENT osslcs assomvn'rmsr'rnoor-arrmncn Oliver D. Broderick, New Orleans, La. ApplicationMay a, 1932. Serial No. 010,211 2 Claims. (01. 2211-80) The object ofthis, my present invention, is the provision of simple but very'eflicient means which is designed to be attached to the illler spoutfor the gas tank of an automobile and which is of such construction asto prevent the siphoning or the withdrawal in any other manner of thegasoline from the. tank without interfering with the free flow of thegasoline into the tank, whereby to render the gasoline in the tank thiefproof.

To the attainment of the foregoing the invention consists in theimprovement hereinafter described and definitely claimed.

In the drawing: Figure 1 is a top plan view of one form of theimprovement.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a horizontal sectional view apgo proximately on the line 3-3of Figure 2.

Figure 4 is a top plan view showing a slightlydiiferent form of theimprovement.

Figure 5 is a sectional view approximaf sly on the line 5-5 of Figure 4,the closure cap for as the filler spout being in position.

Figure 6 is a plan view illustrating another form of the improvement.

Figure 7 is an edge view thereof.

Figure 8 is a sectional perspective view to so illustrate still anotherform of the improvement.

When the filler spout 1, of a gasoline supply tank 2, is short I weld,solder, bolt or otherwise rigidly secure therearound a ring 3 secured toand extending from the lower end of a tube 4. On its outer end the tubeis thickened preferably by having a ring member swaged, welded orotherwise secured thereon and the said thickened portion is exteriorlythreaded for the reception of the flanged closure. In the tube 4,adjacent to the inner or lower end thereof, there are secured metaldiscs 5 and 6, respectively. The discs are each provided with armateslots 7, adjacent to their periphery and the inner walls afforded bythese slots are out at opposite angles. The slots are four in number andprovide therebetween connecting elements which, for the sake ofconvenience, I will refer to as arms '8. The arms 8 on the respectivediscs 5 and 6 are disposed. at angles with respect to each other, or inotherwords, the arms 8 of one of the, discs are arranged approximatelycentrally between the arms 8 of the adjacent The discs are arranged inclose proximity, 65 and the mentioned angle walls provided by the slots7 are cut or notched toward the arms 8,

or rather the portions of the discs in a line with the said arms 8, asindicated by the dotted lines in Figures 3 and 4 of the drawings.- Themetal provided between these angle notches 9 is bent upwardly to aifordsubstantially V-shaped baiile elements 10, and the bailie elements onthe discs are disposed away from each other because of the anglerelation of the parts comprising the arms 8 of the said discs. Thesesubstantially V-shaped baille elements or prongs 10 being arranged at anangle over the openings aiforded by the bending of the said prongsprevent the passage of a hose or any other device through the tube andinto the tank 2 so that the gasoline cannot be siphoned orotherwise-surreptitiously withdrawn from the tank while the arrangementof parts is such as to not interfere with the free flow of the gasolineinto the tank when the latter is to be filled or replenished.

In Figures 4 and 5 the tube 4' is screwed in the fillerspout 1' for thetank 2. In these views I have illustrated only one disc, but obviouslyany desired number of closely related and superimposed discs may beemployed. The disc 11 is provided with arcuate slots 12, ad- Jacent theperiphery thereof, the inner walls afforded by the slots being disposedat opposite angles, and the division walls or what I have termed armsbetween the slots are indicated by a the numeral 14. .The body of thedisc, from points in a line with the plane of the arms 14, is notched toaflord a plurality of prongs 15 that are bent at upward angles, theprongs projecting from the opposite edges of the arms 14 being bent atopposite angles, and one of each of the outer angle prongs is formedwith an additional and short angle prong 18. The prongs afford bailleelements to prevent the insertion of a hose or the like into the tank 2'but the said prongs do not interfere with the free flow of. the gasolineinto the tank.

In Figures 6 and '1 theconstruction slightly diflers. The disc 17 isprovided, from adjacent its periphery, with substantially V-shaped cut-100 away portions 18 and with right-angularly arranged arms 19 betweenthe said cutaway portions 18. In this instance the arms are formed hwith inner extensions which are centrally connected and which extensionsare indicated for distinction by the numeral 20. The body of thedisc,'at the cutaway portions 18, is provided with v-shaped notches andaiford therebetween-substantially v-shaped bendable prongs 21, and

the body of the disc between the arm exten-- 510155 the base of theprongs 21 is cut away to provide other and inner V-shaped bendableprongs 22. The inner and outer series or prongs 22 and 21 are bent atopposite angles and likewise these prongs are centrally bent uponthemselves so that the same are not only V-shaped in plan but arelikewise substantially I-shaped in cross section. These prongs a!- tordbaiiies to prevent the entrance of a hose or the like into the tank, butthe construction is such as to .not interfere with the ,tree flow ofgasoline into the tank.

In Figure 8 the tube 23, which is secured to the tiller spout, hasarranged therein a plurality of closely related but superimposed discs24. The discs are oppositely directed, that is, the intermediate dischas its straight edge disposed between the straight edges of the outerdiscs, and all of these discs are formed with series 01' substantiallyV-shaped slots, the metal bounded thereby being bent to afford the samewith substantially -V-shaped baflie prongs 25. The baiiie prongs 25 onthe. outer discs are directed toward one side of the tube 23, while thebaflie prongs on the intermediate disc are directed toward the oppositeside of the tube.

In all forms 01 my improvement it will be noted that the tree flow ofthe gasoline into the tank is not in any ways interfered with and, as amatter-ot-fact, the discs tend to prevent the splashing of the gasolinedelivered into the tank. The construction renders the tank positivelytheft proof and it is thought that when the ioregoinghas been carefullyread in connection with the accompanying drawing the device willbe'understood and appreciated by those skilled in the. art withoutfurther detailed description.

- Having described the invention, '1 claim:

1. A tube'providing a gasoline inlet for, the gasoline tank or anautomobile orthe like and designed to be closed by a cap, superimposeddiscs fixedly secured in the tube adjacent to the bottom thereof, saiddiscs'having series of angularly related substantially V-shaped slotsand the metal bounded by the slots bent at upward anglesto overlie theopenings 'th'erehelow, and to aiford baflie prongs and the baiiie prongson the respective discs being arranged out ot a line with each other.

2. A tube providing a gasoline inlet for the construction and advantagesor my improved gasoline tank of an'automobile or the like and designedto be closed by a cap, superimposed" discs fixedly secured in the tubeadjacent tothe bottom thereof, said discs having series of angularlyrelated substantially V-shaped slots and the metalbounded by the slotsbent at upward angles to overlie the openings therebelow, and to affordbaiiie prongs and thebame prongs on the respective discs being arrangedout ofia line with each other and said baifle discs being both V shapedin plan and in cross sections a OLIVER n.
